REINKE WIRE ATTACHING DEVICE Filed Aug. 23, 1928Patented Aug. 12, 1930 UNITED STATES PATENT OFFICE WALDEMAR REINKE, FCHICAGO, ILLINOIS, ASSIGNOR T0 JUSTRILE MANUFAC- TUBING COMPANY, 013CHICGO, ILLINOIS, A CORPORATION OF ILLINOIS WIRE-ATTACHNG DEVICEApplication filed August 23, 1928.

This invention has for its object to provide a simple, cheap andeflicient device for securing electric wires along the trim of rooms ofbuildings without injuring the trim or the walls as by driving staples,brads or screws into the same, and which is of such a nature as topermit of its use by unskilled persons to quickly and neatly stringlamp-cords and the like in the home along base-boards, under windowcasings, etc., to thus maintain such cords o1f the floor and out ofreach of brooms, Z1PGt sweepcrs, vacuum cleaners and the The inventionmay be variously embodied and in the accompanying drawings, I haveillustrated a plurality of embodimcnts of the same. In the drawings:

Fig. 1 is a fragmentary perspective sectional view showing a Wall andtrim go equipped with wire attaching devices constructed in accordancewith the invention.

Fig. 2 is a fragmentary Vertical section of the wall and trim shown inFig. 1 with a device of my invention engaged therebetween.

Fig. 3 is a front elevation of the wire attaching device in itspreferred embodiment.

Fig. 4 is a perspective view of the metalfic part of the device.

Fig. 5 is a side elevation of the metalfic part of the same.

Fig. 6 is a front view of an insulation strip employed.

Fig. 7 is a perspective view of a modified form of construction of thedevice.

In building construction it is the usual practice to apply the wood ormetal trim, such as base-boards, door and window casings, picturemoulding, etc. after the plastering of the walls has been completed, thesaid trim overlapping the plastcr and, generally, leaving shallow freespaces between the plaster and the opposed surface of the trim.

Thedevice of this invention is designed to take advantage of this freespace by providing a wire engaging substantially semicylindrical member1 having a shank 2, the latter being adapted for insertion in said freespace. Howevcr, in order that said shank may be firmly held in place insaid free spac without the use of fastening devis,

Serial No. 301,685.

I provide for a wedge like engagement of said shank betwecn trim andplaster. This, in the structure shown in F igs. 1 t0 5 and 7 inclusive,is obtained by causing the plane of the flat shank 2 t0 intersect thearcuate formation 1 at some distance from its free end. At the latter Iprovide a flange or lip 3 which bears upon the Wall and slides along thesame without scratching or marring the same as the shank 2 is insertedbetween trim and plaster. During such insertion the shank 2 will be bentas shown in Fig. 2 so as to exert pressure upon the plaster behind thetrim and upon the corner of the latter opposed to the plaster, it beingunderstood, of course, that the device is made of a spring metal such assteel, brass or the-like.

By refercnce t0 Fig. 5 it Will be noted that the curved or hookformation 1 of the device is ofiset outwardly from the outer face of theshank 2 and that the lip 3 at outer end of said formation 1 is offsetinwardly from the plane of the other or inner face of said shank 2,these faces being termed inner and outer With respect to this positionon the Wall or surface against which the lip 3 bears as shown in Figs. 1and 2. it will also be noted that the shank 2 is devoid of any securingmeans such as brads, screws and the like.

Obviously, the shank 2 of the device may be bent t0 vary the degree, ofoffset o f the lip formation 3 from the plane of its inner face tobetter accommodate the clip t0 engage in spaces varying in width.

It Will be obvious that the recesscs 4 of the shank 2 serve t0 weakenthe latter laterally and increase its flexibility at this point. Thishas been found advantageous aside from the function of said recesscswith respect to retaining the strip 5 of insulation in place, in that,in instances where the crack or space receiving the shank 2 is verysmall, the insertion of the said shank is less resisted and the flcxingthereof confined alm0st entircly to this weakened portion.

The structure of Fig. 7 is very similar to that of Figs. 1 to 5inclusive in that the arcuate porton 12 terminates in the fiat shank 13from which the spring tongue 14: is struck,

the latter being curved bctween its ends and naviflg, preferably, i1ssree on& opposei to flze upper Wal1 of he slot 15 resulting from thestrikin out of the tongue 14 from the shank 13. ad tongue 14 preferabyeztens outwardly from the shank to beau: upon the trim surface opposedto the piaster while its fiat portion beurs on the p1aster.

I daim as my invention A wire engaging clip for e1ectric wre comprisinga plane shank devoid of securng means and terminating at one end in abock formation to receive a wre, said hook formaton being ofisetoutwardly from the our face of said shank and termnating in a lipformation ofiset inwardly-from the plane of the inner ace'of said shank.
